| 20100196012 | NETWORK SYSTEM - Provided is a network system for controlling devices which operate in response to an infrared signal. The network system includes modules and a home server. The modules output the infrared signal for controlling the devices in response to command data or analyze path information of the command data, forward the command data to next one of the modules, and receive infrared control signals generated by the devices. The home server includes ID numbers of the modules and the path information of the command data for allowing the command data to reach each of the modules and outputs the command data or receives the infrared control signals. Therefore, the network conveniently control the devices using the infrared control signal even when the modules are too distant from the home server for the infrared signal to reach the devices at a time or obstacles are placed in front of the modules. Also, the network system performs authentication processes among the modules using time information to prevent the modules from malfunctioning by another infrared signal or command data. | 08-05-2010 |
